a shortage of silicon and microprocessor companies willing to pay up to $70 per kilogram of electronics grade silicon is causing the solar energy revolution to suffer as a result. Because cheap solar-cell grade silicon currently is not produced by manufacturers for ~$10 a kilogram, both the microprocessor manufacturers and solar cell producers are buying the same electronics-grade silicon, causing a major silicon shortage. In 1998, supply and demand was almost the same but ever since them demand has risen in comparison to the supply which has remained at a constant 2000-2500 tons per year and in 2005-2010, the amount of demand could nearly triple, even quadruple the availability. Hopefully new ways to extract silicon will be developed before this becomes a big problem. Now that you've read a little bit about the current problem, what would you want more: solar power or computer processors? Or would you have both and maybe hope for processors that do not use silicon later in life?
